The Fenix isn't a "dumb" watch. As far as battery life, Garmin has recently been making some digs at Apple about Garmin watches battery life being in days instead of hours. The Fenix has something around a month of battery life, depending on features you use. The Fenix Solar can, again depending on features enabled, have "unlimited" battery life if it is sunny.
Not sure what maps it has, it does have some mapping ability, I know it advertises having golf course maps. I'm unsure what other map features it has. I've been looking at the Garmin watches (Instinct 2 mostly), but I don't really care about mapping features.
